In the era of high martial arts, everyone awakens their innate power at eighteen.
Some awaken divine weapons, some command thunder and fire, and some form contracts with exotic beasts.
What Xu Zheng awakened was a city.
More absurdly...
The nation is set to officially abandon that city in thirty days.
More than twenty thousand people are evacuating. Factories have shut down, the garrison is moving south, and the city walls and boundary system are close to collapse.
Everyone thinks an innate power like this is useless.
Until Xu Zheng discovers:
The city walls are his bones, its energy is his heart, and its roads are his meridians. The entire city of Linyuan can become his strength.
Other people cultivate to grow stronger themselves.
Xu Zheng cultivates to bring a dying city back to life.
Later, the abandoned fortress city lights up again, and lost territory returns to human hands piece by piece.
The national border, which had been retreating for decades, finally begins to move back the other way.
